White fused alumina powder for casting is produced in utilization of the advanced production equipment and special technology.
It is characterized by less impurities, low porosity, good bulk stability and thermal shock resistance in place of zirconium powders as the molding material of investment casting.
It can be also used for silica sol technology, large-scale steel castings, especially for alloy castings, core sand, coatings, etc.
